Functions and Processes in Service Transition P1

Transition Planning and Support

Introduction

  • The goals for transition planning and support include:


    • Planning and coordinating resources in order to ensure that the specifications of the Service Design are realized.


    • Starting with the transition phase, identify, manage and limit risks that could interrupt the service.


  • The objectivesfor transition planning and support include:


    • Plan and coordinate people and means within the frameworks.


    • Make sure that everyone applies the same frameworks and standards.


    • Report service issues.


    • Provide clear and extensive plans.


    • Support transition teams and others involved.


    • Controlled planning of changes.


    • Report issues, risks and other deviations.


  • Scope


    • The following activities are included in the scope of transition planning:


      • Include design specifications and product requirements in the transition plans.


      • Manage:


        • Plans.


        • Supporting activities.


        • Transition progress.


        • Changes.


        • Issues.


        • Risks.


        • Deviations.


        • Processes.


  • Scope


    • The following activities are included in the scope of transition planning:


      • Manage:


        • Supporting systems and tools.


        • Monitor Service Transition achievements.


        • Communicate with clients, users and stakeholders.


  • Value for the business


    • An integrated approach to planning improves the alignment of transition plans with the customer, service provider, business and change project plans.


  • Basic concepts


    • The Service Design Package(SDP) contains the following information required by the service transition team:


        • Applicable service packages (e.g. core service package, service level package).


        • Service specifications.


        • Service models.


        • Architectural design required to deliver the new of changed service including constraints.


        • Definition and design of each release package.


        • Detailed design of how the components will be assembled and integrated into a release package.


  • Basic concepts


    • The Service Design Package(SDP) contains the following information required by the service transition team:


      • Release and deployment plans.


      • Service acceptance criteria.


    • In the release guidelines and policy, the following subjects are addressed:


      • Naming conventions, distinguishing release types, such as: major release, minor release and emergency release.


      • Roles and responsibilities.


      • Release frequency, the expected frequency of each type of release.


  • Basic concepts


    • In the release guidelines and policy, the following subjects are addressed:


      • Approach for accepting and grouping changes in to a release.


      • How the configuration baseline for the release is captured and verified against the actual release contents e.g. hardware, software, documentation and knowledge.


      • Entry and exit criteria and authority for acceptance of the release into each Service Transition stage and into the controlled test, training, disaster recovery and production environments.


      • The criteria authorization for leaving Early Life Support (ELS) and handover to service operations.

Activities, methods and techniques

  • The activities for planning and support consist of:


    • 1.Set up transition strategy.


    • 2.Prepare Service Transition.


    • 3.Plan and coordinate Service Transition.


    • 4.Support.


  • 1.Set up transition strategy


    • The transition strategy defines the overall approach to organizing Service Transition and allocating resources.


    • Aspects that may be addressed in the transition strategy are:


      • Purpose, goals and objectives.


      • Context and scope.


      • Applicable standards, agreements, legal, regulatory and contractual agreements.


      • Organizations and stakeholders involved in the Service Transition.


      • Framework for Service Transition.


  • 1.Set up transition strategy


    • Aspects that may be addressed in the transition strategy are:


      • Criteria for success and failure.


      • People; roles and responsibilities.


      • Approach including transition model, plans for managing changes, assets, configurations and knowledge; transition estimation; preparation; evaluation; error handling; KPIs.


      • The products (deliverables) that are the result of the transition activities such as transition plans, schedule milestones, financial requirements.


  • 1.Set up transition strategy


    • The SDP defines the various phases of the Service Transition. Theses may consist of:


      • Acquiring and testing components.


      • Testing service release.


      • Service Operation ready test.


      • Rollout.


      • ELS.


      • Review and close service transition.


  • 2.Prepare Service Transition


    • Preparatory activities consist of:


      • Review and acceptance of inputs from other Service Lifecycle phases review and check the input deliverables e.g. SDP, Service Acceptance Criteria (SAC) and evaluation report.


      • Identifying, raising and scheduling RFCs.


      • Checking the configuration baselines are recorded in configuration management before the start of service transition.


      • Checking transition readiness.


  • 3.Plan and coordinate Service Transition


    • A service transition plan describes the tasks and activities required to release and deploy a release into the test environments and into production including:


      • Work environment and infrastructure.


      • Schedule of milestones.


      • Activities and tasks to be performed.


      • Staffing, resource requirements, budgets and timescales at each stage.


      • Lead times and contingency.


  • 3.Plan and coordinate Service Transition


    • Good integrated planning and management are essential to deploy a release across distributed environments and locations into production successfully.


    • An integrated set of transition plans should be maintained that are linked to lower level plans such as release, build and test plans.


    • It is a best practice to manage several releases in a program, with each significant deployment run as a project.


  • 3.Plan and coordinate Service Transition


    • Implement quality reviews for all Service Transition, release and deployment plans. Questions that might be asked are:


      • Are the service transition plans and release plans up-to-date, authorized and are the release dates known?


      • Were any risks related to impact on costs, organization and technology taken into account?


      • Are new configuration items (Cls) compatible with each other and with configuration items in the target environment?


      • Are the people who need to work with it sufficiently trained?


      • Have potential changes in the business environment been taken into account?


  • 4.Transition process support


    • Service Transition advises and supportsall stakeholders.


    • The planning and support team provide insight for the stakeholders regarding Service Transition processes and supporting and tools.


    • In addition, the team will perform management/administrationof changes, work orders, issues, risks, communication and deployment.


    • The team will also update stakeholders regarding planning and process.


  • 4.Transition process support


    • Finally, Service Transition activities are monitored:


      • the implementation of activities is compared with the way they were intended (as formulated in the transition plan and model).
